I just wanted to say how pleased I was with both the quality of the windows and the service I received when ordering them. They fitted simply and were a pleasure to install too. It’s always a worry when buying things blind on the internet, but I can honestly say that I’m 100% happy with everything. Even my wife said what a difference they make and visually, you hardly notice they are there.

Best investment in my property so far! I live in a Grade II listed building, which was built in 1850, so double glazing is not permitted. I have single-pane sash windows which used to have a lot of condensation on them, rattled as the draughts came in and were useless against noise. Luckily, I discovered Clearview at the end of last year. The ordering and delivery were easy with excellent communication throughout. Since I fitted the units condensation has been eliminated, no more draughts and external noise has been greatly minimised. The windows are well made and easy to install. They’re so good I’ve yet to put the heating on this year

Can I say how pleased we all are with the secondary glazing at The Cottage, Badminton. The windows in the Library, Office and the lockable lift outs for the skylights look really good. Please thank Wez & Dan for me for all their hard work and in keeping the Cottage tidy whilst fitting. Many thanks to you as well for putting our minds at rest from the start of the project. The Cottage is now warm and toasty with new heating and wood stove installed in the library. What a transformation!!!

I am writing to you thank you for your excellent service throughout my recent purchase. The advice offered and pre-delivery service was fantastic. It is refreshing dealing with professionals and I believe this company is an excellent example of how everyone should be going about business. The secondary glazing has made a significant difference and I am very happy with the price.

Clearview customer service is outstanding. This is an excellent product that can be installed by any competent DIY'er. My units are single pane hinged double glazing and fitted in a listed building. They are invisible when viewed from the outside and so unobtrusive on the inside.

From the start I was confident about this company. I had a non standard requirement and they spoke at length about it. Furthermore they arranged for a delayed and specific delivery to fit in with my availability. I was able to fit and trim the unit in 2.5 hours and for anyone with DIY skills it is easy enough. It has reduced noise considerably despite not being at the recommended distance from the existing window. It is also invisible! I have attached photos and it is difficult to see the additional unit! Highly recommended this company.

From start to finish, our dealings with Clearview Secondary Glazing could not have been better! They proved to be a thoroughly professional business, who carry out an all round first class service by not only providing and installing a superb product but also by explaining everything in non-ambiguous terms; keeping the customer informed at every stage; turning up when they say they will and for being, well, just very nice people! Worth every penny! Thank you very much Andrew and Craig (and those behind the scenes we didn't get to meet!)

I'm completely made up with my new Clearview Secondary Glazing windows. Not feeling confident with your DIY skills? Fear not, as from start to finish I felt totally supported by the team at Clearview SG. I had loads of questions about the process (measuring, ordering, installation etc) but no question was ever too much trouble for them. I made a few mistakes when measuring, but they check, double check and triple check before they begin manufacturing. The windows look great and work perfectly. I would recommend them to anyone. Thanks heaps to Andrew, Deborah and the rest of the team. Brilliant!

I would like to take the opportunity of thanking all at Clearview for the supply of my secondary glazing units. We have an older style house with aluminium framed double glazed windows in hardwood surrounds and although they suit the property they are not as efficient as modern glazed windows. We didn't want to upgrade the windows as UPVC frames would look wrong. I had fitted some DIY Polycell units many years ago but decided that we would now like to do the job properly with toughened glass and the ability to open the centre panel only to get to the fanlight, these 3 panel sliding units really do the job. After a lot of online searching we chose Clearview and am so pleased we did, the service has been great, from the online quote to placing the final order, we have been kept in touch all of the way even to the delivery driver phoning to fix a delivery time. I have finished the installation and would have no difficulty in recommending both your product and your company. Many thanks David Terry.

Bought 2 units for our front bedrooms as we are on a noisy main road. Installed them yesterday and the difference in noise is amazing. I went for the 6.4mm laminated glass and positioned the units on the front of the window sill to give maximum gap.

I would just like to say what a fantastic product the Clearview secondary glazing has been in our bedroom, without going over board it has improved our quality of life literally overnight, we have spent a lot of years complaining about traffic and human noise from outside and the secondary glazing has pretty much solved the problem, not to mention the lack of condensation. Great solid product and helpful advice from your staff. Easy to fit from a lay mans point of view, I have decided to go with another 2 windows down the noisy side of the house, will be in touch.

We wanted to express our sincere thanks for making the whole process run so smoothly - from our initial contact with you, through to the actual installation of the units. Throughout the entire planning stage, you have been extremely helpful and courteous. And, in relation to the actual installation, we have absolutely nothing negative to say. They were polite, professional, worked hard to keep any disruption to a minimum, readily answered any questions we had (of which there were a few) and, to sum up, it was a pleasure having them in our home. By the time they were ready for leaving, they had done such a good job cleaning up after themselves, that the only thing to show for their visit was the fact that we now had our wonderful secondary glazing in place. And, on this note, we are absolutely thrilled! Other than the obvious benefits from the sound insulation, you wouldn't know the windows were there - they are so unobtrusive, it's incredible! It has made a huge difference in cutting down the noise from the traffic, and also noise (previously heard, but no longer) from people going past, or from youngsters playing out.

Our bedroom overlooks a railway line, so we were primarily looking for acoustic insulation (we’d had secondary glazing in our last home, so knew how effective it was). After some online research, we went with Clearview this time, as their prices are competitive, their online quotation system quick and easy, and – perhaps most importantly – their customer service responsive and helpful. As it happened, here were a couple of glitches (on my part) with measuring and specifying, which Andy at Clearview ironed out for me with no fuss. Once ordered, the product arrived on time, and has proved highly effective at reducing the noise. I actually enjoy watching trains go by in near-silence, and have since ordered a similar unit for our living room, to repeat the experience! I can thoroughly recommend secondary glazing in general, and Clearview in particular.

The secondary glazing has improved the insulation of our house. It’s much more comfortable. I can now work close to the windows without the discomfort of draughts. As a surveyor, I can tell you that Clearview’s work is high quality.

The lounge is much warmer since secondary glazing was fitted, and the condensation has stopped. We have also noticed a reduction in noise from the main road outside. We really like the fact that the secondary glazing does not detract from the look of the bay, inside or out. We don’t notice it.

We had secondary glazing fitted in January, and immediately noticed the benefits. Our dining room is much warmer, and quieter. But, the most welcome change is that condensation no longer drips from the bay window. Clearview were great to deal with, we will be calling them again to look at the other windows in our house.

I had a condensation problem in my downstairs cloakroom, so I tackled this first. The secondary glazing looked great and it solved the problem. You get expert help, they keep you up to date on delivery (always on time) and the end product is first class, at a fraction of the cost of new glazing. Highly recommended.

Good quality windows, acoustic glass does the job well. We fitted these ourselves, but the website and customer service team make sure you've been informed of everything you need to do to measure correctly and that you've chosen the right options for openings. Not the cheapest, but all in all great service, would recommend to anyone.

I've just finished a self-fit project on our listed cottage, of a mixture of horizontal sliding and lift-out units. The team at Clearview were helpful and efficient throughout, fitting instructions and tips were comprehensive and clear, and phone queries were answered promptly, with helpful advice and suggestions. The resulting sound insulation is remarkable - we live next to a sometimes noisy pub - and the outside appearance is unchanged. Inside the finish is neat and one hardly notices that there is secondary glazing there. Very satisfied.

Fitting was a breeze – if you can handle a screwdriver, you can fit them yourself. Immediately noticeable was the reduction in traffic noise from the fairly busy road. The added bonus of the extra insulation they provide is noticeable too, but best of all, after 4 nights now, I have not had a single drop of condensation on the original double-glazed windows yet. Anyone considering buying these but having second thoughts or doubts? Don’t delay any longer. Not only is it a great product, but the sales staff were very patient and helpful with me at the start of the process.

The window is perfect it cuts out all the road noise and has already made the room warmer. The design and workmanship are impressive. We have a listed building and even though the secondary glazing is a sash unit, it is invisible from the outside. Delivery was on the day promised and it took me just 40 mins to install. Congrats on a great product. I will be ordering more units.

What the company offered was perfect for us because we wanted to retain the external character of our home, while keeping heat in, and noise out. Megan’s room is at the front of our house, and she has alway been a light sleeper, so sounds of cars and dustbin lorries were constantly waking her. But since the secondary glazing has been fitted she has slept much better.

The secondary glazing is now all installed and looks great but most importantly, at least for me, the noise insulation is amazing.

The windows were easy to install and look neat and in tune with my sash windows.

Problems with your windows? Help us to find the perfect solution for your needs.

My client wanted a solution to a problem regarding excessive sound being experienced within a large office complex, whilst having conferences and meetings in a large second-floor room with single glazed aluminium windows on two elevations. During my research, I found Clearview to be knowledgeable and very helpful in solving my client’s problem and alternatives with prices to meet the budget available. I was provided quality support throughout the process. The product was delivered on time, as promised with good protective wrapping. The installation was extremely easy, with quality materials and instructions. Once installed, the difference was amazing and whilst showing the client the finished job, a very large articulated lorry being towed by a similarly large tow truck rolled past the conference room within 3 m. The silence was palpable, the client was over the moon and hopefully impressed enough to want this system throughout this large office complex. Watch this space! Many thanks to the Clearview team for making this such an easy process and special thanks to Lianne and Deborah for putting up with my blond moments during the survey and ordering stage. As a shopfitter/office refurbishment specialist, we provide a service and believe that the client is king and by providing a good service the client will happily use us again.

If you have an older house with "special" windows which are struggling to cope with our ever changing weather conditions, I recommend that you seriously consider Secondary Glazing. Have a look at Clearview's web site first as it is really helpful, then if you are in any doubt speak to them. The Ladies there are even more helpful. Do not rule out fitting them yourself as the quality of the units supplied is first class. The key to it success is in the measurement of the windows you wish to fit. Measure and then check again. I would recommend trying just one first before embarking on a full scale re-fit as it will give you more confidence in the product. I had a condensation problem in my downstairs cloakroom, so I tackled this first. It looked great and it solved the problem.
